Abstract
Description
Die Erfindung betrifft einen flüssigkeitsgekühlten Zylinderkopf mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a liquid-cooled cylinder head having the features of the preamble of patent claim 1.
Zum technischen Umfeld wird beispielsweise auf die
Ein solcher, aus dem Stand der Technik bekannter Zylinderkopf weist keine oder nur eine geringe Variantenvariation von möglichen Kühlmittelströmungsführungen auf.Such, known from the prior art cylinder head has no or only a small variation variation of possible coolant flow guides.
Weiter ist aus der deutschen Offenlegungsschrift
Mit einem derartigen Zylinderkopf ist zwar eine zwangsgeführte und flache Heißzonenströmung möglich, jedoch ist die Herstellung eines geteilten Zylinderkopfes für eine Brennkraftmaschine relativ aufwändig und teuer.Although a positively driven and flat hot zone flow is possible with such a cylinder head, the production of a split cylinder head for an internal combustion engine is relatively complicated and expensive.
Aufgabe der vorliegenden Erfindung ist es, o. g. Nachteile zu vermeiden.The object of the present invention is o. G. To avoid disadvantages.
Diese Aufgabe wird durch die Merkmale im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is solved by the features in the characterizing part of patent claim 1.
Durch die erfindungsgemäße Ausgestaltung ist eine zwangsgeführte und flache (unmittelbar am Brennraumdach) Heißzonenströmung möglich, ohne Funktions- oder Gewichtsnachteile. Darüber hinaus werden die Sandkernstabilität der Kühlmittelräume und die Strukturfestigkeit des Zylinderkopfes wesentlich verbessert.The inventive design a positively driven and flat (directly on the combustion chamber roof) hot-zone flow is possible without functional or weight disadvantages. In addition, the sand core stability of the coolant chambers and the structural strength of the cylinder head are significantly improved.
Weiter ist durch die Ausgestaltung gemäß Patentanspruch 2 eine fast unbegrenzte Variantenvariation von möglichen Kühlmittelströmungsführungen über Speisungs-, Ein- oder Ausströmanschlüsse möglich.Next, an almost unlimited variant variation of possible coolant flow guides on supply, inlet or Ausströmanschlüsse is possible by the embodiment of
Die Ausgestaltungen gemäß der Patentansprüche 3 und 4 sind besonders bevorzugte Ausführungsvarianten.The embodiments according to
Die mögliche Strömungsvariantenvielfalt wird mit den Ausgestaltungen gemäß der Patentansprüche 5 und 6 nochmals deutlich erhöht.The possible flow variant variety is again significantly increased with the embodiments according to the
Gemäß Patentanspruch 7 kann die erfindungsgemäße Ausgestaltung an jedem Zylinderkopf Einsatz finden, unabhängig von der Anzahl der Zylinder der Brennkraftmaschine.According to
Im Folgenden ist die Erfindung anhand eines bevorzugten Ausführungsbeispieles in zwei Figuren und anhand einer Tabelle näher erläutert.In the following the invention with reference to a preferred embodiment in two figures and with reference to a table is explained in more detail.
Im Folgenden gelten für gleiche Bauelemente in beiden Figuren die gleichen Bezugsziffern. Below, the same reference numerals apply to like components in both figures.
An dieser Stelle sei erwähnt, dass in
Erfindungsgemäß ist geodätisch unter dem Kühlmittelkanal
Weiter weist der erfindungsgemäße Zylinderkopf
In einem weiteren besonders bevorzugten Ausführungsbeispiel sind der Kühlmittelkanal
Ergänzend sei noch erwähnt, dass der erfindungsgemäße Zylinderkopf
Erfindungsgemäß sind der Kühlmittelkanal
Wie bereits eingangs erwähnt, sind in
In folgender Tabelle 1 sind Varianten von Kühlmittel-Strömungsführungen am Beispiel einer Zweizylinder-Brennkraftmaschine mit einem Vier-Ventil-Zylinderkopf dargestellt. Horizontal sind die Eigenschaften (wie das Kühlmittel ein-, durch- oder ausströmt) dargestellt und vertikal unterschiedliche Strömungsvarianten, in vorliegender Tabelle elf Strömungsvarianten, wobei die Tabelle nicht vollständig ist, d. h. es sind noch wesentlich mehr Strömungsvarianten möglich.In the following table 1 variants of coolant flow guides are shown using the example of a two-cylinder internal combustion engine with a four-valve cylinder head. Horizontal are the properties (as the coolant enters, flows through or out) and vertically different flow variants, in the present table eleven flow variants, the table is not complete, d. H. There are still significantly more flow variants possible.
Zu den Eigenschaften zählen die Speisung, die Einströmung, die Ausströmung und die Ausführung des Zylinderkopfes, die immer mit einem Kühlmittelkanal
So kann die Speisung (von wo kommt das Kühlmittel), wie in Tabelle 1 dargestellt, mit Kühlmittel aus dem Kurbelgehäuse
Die Einsträmung (wo strömt das Kühlmittel ein) des Kühlmittels kann im Kurbelgehäuse
Gleiches gilt für die Ausströmung (wo strömt das Kühlmittel aus) des Kühlmittels aus dem Kurbelgehäuse
In der Tabelle 1 sind unterschiedliche Kühlmittelführungen zeilenweise jeweils mit einem X gekennzeichnet, wodurch unterschiedliche Varianten entstehen. In Abhängigkeit der jeweiligen Brennkraftmaschine
Durch die erfindungsgemäße Ausgestaltung ist eine sehr gute Darstellung einer zwangsgeführten und flachen, unmittelbar am Brennraumdach angeordneten, Heißzonenströmung möglich. Weiter ergeben sich keine Nachteile für Strömungsquerschnitte und Sandkernstabilität bei der Kernmontage des Kernpakets (Einlegen der Einlass- und Auslasskanalkerne), durch die geteilten Kühlmittelräume
Insgesamt ermöglicht die erfindungsgemäße Ausgestaltung eine sehr hohe thermomechanische Bauteilbelastbarkeit, die beispielsweise geeignet ist für eine Hochaufladung unter Beibehaltung hoher Robustheit/Lebensdauer durch sehr gezielte kühlungsintensive Strömungsführung in Verbindung mit einer hochfesten Struktur. Overall, the inventive design allows a very high thermo-mechanical component load capacity, which is suitable, for example, for a high charge while maintaining high robustness / life by very targeted cooling-intensive flow guidance in conjunction with a high-strength structure.
Die Erzielung dieser Vorteile erfordert ggf. die Inkaufnahme geringer Gewicht-/Kostennachteile verursacht durch die Trennwand und evtl. zusätzliche Verschlusselemente
